Intranodal lymphangiography and interstitial lymphatic embolization to treat chyluria caused by a lymphatic malformation in a pediatric patient.

Chyluria is characterized by chyle in the urinary tract and often presents as milky-white urine. We present a case of chyluria from a lymphatic malformation in a 13-year-old boy diagnosed using dynamic intranodal contrast-enhanced magnetic resonance (MR) lymphangiography. This report demonstrates the utility of intranodal lymphangiography and interstitial lymphatic embolization to treat a pediatric patient presenting with persistent chyluria. Glue migration into the urinary collecting system is a potential complication of this procedure that can be mitigated by adjusting the n-butyl cyanoacrylate dilution with Lipiodol.
